AApplication filed February This invention relates to an improvement inrouters, and the like, vand has for an objecttol provide betterzmeansfor mounting the motor constitutingvthe source of power, with respect tothe element ofthe machine .receiving the drive from `the motor.

Another object consists in providing a universally adjustable y mountingfor the motor. y

Another object consistsinprov'iding such a mounting which isconveniently supported from the machine proper so as to facilitate thedrive.

Another object consists inprovidingy certain improvements in theform,.construc tion -and arrangement of the several parts .whereby'theabove named and'othervobjects may effectively be obtained.

A practical embodiment is represented in the accompanyingdrawings, inwhich Fig. 1 represents a detailvplan'view of parts disclosing myinvention;

A second bracket v7 is 'fixed to and; projects from the bed 1 of Ithemachine, Iand has a substantially circular ertremity. `This vbracket isdesigned for the mounting ,ofthe electric motor 8.

Referring to Fig. 4, it will be seen that the parts are the saine lasdescribed in connect-ion with Figs. 1 to Sinclusive, but there is avV'slight dilierence in application, in that the screws 10 are reversedsothat their heads stand up against the bottom of the plate 9*. Thisprovides for an increased elevation of the said plate, and hence, of themotor it carries. `lIhe loperation of the partsis the i same als inconnection with the disclosure of Figs. 1 to 3 inclusive.

Referring` to'theform shown in Fig. 5, the construction andV operationare the same as the form shown in Figs. 1 to 3 inclusive, except thatthe disc 9 and cap screws 9** are j 'omitted` The motor is bolted orotherwise suitably secured directly to the plate 9*, without any slidingadjustment thereupon.

It will be understood that various Vchanges may be resorted to in theform,`construction, andarrangement of the several parts'with` Y outldeparting fromV the spirit and scope of my invention, and-hence I donot intend to Y be limited to the details herein shown and describedeXcept'as they may be included in the claims.
